ORE-SEPARAT 0R1.

To all whom it may concern:

Be it known that I, SAMUEL MAN, of the city of Chicago, in the county ofCook and State of Illinois, have invented new and useful Improvements inAmalgamators or Separators by which the Precious Metals may be Separatedfrom Quartz, Rock, Sand, Ore, or any other Substances; and I do herebydeclare that the following is a clear and exact description of the same,reference being had to the accompanying drawings, making a part of thisspecification, in which Figure 1, shows the exterior of the machine inperspective. Fig. 2 is the cover or concave underwhich the cylinderoperates. Fig. 8, represents the outer surface of the cylinder. Fig. l,is an end view of the revolving cylinder, showing the internalarrangements. Fig. 5, shows a longitudinal section of cylinder with boththe internal and external mechanism.

The nature of my invention consists in the construction, and arrangementof a revolving cylinder, having at one end, a conical elevating wheelwith spiral buckets, also spiral or screw flanges, and a series oflongitudinal leaves or projecting wings, on both the external andinternal surfaces, the straight part running horizontally between twoconcave surfaces, they forming a smooth hollow cylinder, in which themercury and minerals are retained while in the process of amalgamation,and separation.

To enable others skilled in the art, to make and use my invention, Iwill describe it more fully, referring to the drawings and the letters,marked thereon.

The frame, and receptacle of my improved amalgamator, or separator ofthe precious metals from other substances, may be made of metal, or ofany other material that will retain the mercury, as seen in (Fig. 1,)the main body (A,) being in the form of a trough, or concave, placed ina horizontal position, and supported on legs, or brackets (i, 11,) ateach end. Into the concave is placed, so as to revolve, a peculiarlyconstructed hollow cylinder (B,) hung on the journals (p, 0,) shown in(Fig. Over the cylinder (B,) is fitted a cap, or concave cover (0,) asshown in (Fig. 6) detached, but when in its place on the machine helpsto complete the circle, for the cylinder (B,) to revolve in. Therevolving cylinder (B,) is made hollow, of any size, and length desired,having a shaft (4,) running longitudinal through the center of itforming the journals (p, 79,) at both ends, which have their bearings inboxes, secured inside of the trough (A,) so that there is no leakage.The cylinder (B,) is supported central, and secured to the shaft, orarbor (g,) by curved wing shaped arms (t, t, t,) seen in (Fig. 4). Atthe the driving end of the cylinder (B,) is a cone shaped flange (3 ofabout twice the diameter of the cylinder which forms the end rim of aninclined elevating wheel On the surface of this cone shaped flange (y,)toward, and extending to the internal arrangement of the revolvingcylinder (B,) are a series of curved buckets (k, 70, 7c, 7a,)which arecovered with another cone shaped flange (Z,) extending from theperiphery of the elevating wheel (m,) to the surface of the cylinder(B,) so that by the revolving of the same, the contents are elevated bythe buckets (7c, 70,) above the cylinder, and by their gravity, aredischarged into it, where they are thoroughly agitated and mixed, bybeing drawn along by the screw flange (w, w, 'w,) and the action of thewings (a2, w,) as seen in 5,) until discharged at the other end, whenthey again are brought in contact with wings or flanges (o, '21,) on theouter surface of the cylinder, so that the agitation is still kept up,to a greater degree, in the trough, until it is carried along by thespiral flange (.9, s, 8,) on the outer surface of the cylinder, till thedirt and refuse material is carried ofl by a flow of water.

The elevating and discharging wheel, and cylinder are put in motion by acogwheel (0,) fastened to the shaft (9,) running inside of the box.There is a pinion (1a,) driven by a band pulley (7b,) which works themachine by power, or it may be operated by hand by putting a crank tothe pulley shaft.

The end or receiving part of the machine (B,) is enlarged to admit ofthe turning of the elevating and discharging wheel (m,) and is dividedinto three compartments, by sliding partitions (c, d, and e.) The endspace is for the gear wheels (n, and 0) to work in. The space betweenthe partitions (c and c,) is the place where the materials are put intothe machine, as also the pit for the wheel (172,.) The space between thepartitions (c, and (Z,) is the water course, from which the refuse isdischarged,

The operation of my machine is very simple and eflicient. The substanceto be amalgamated, and separated, is raised by the curved buckets, whichby their inclined position discharge their contents into the inside ofthe revolving cylinder where they are thoroughly agitated, and mixedwith the mercury until it is discharged from the end into the trough, orstationary cylinder,

where it continues to be more agitated as it is carried back by thewings and spiral flanges on the surface of the cylinder, to the spacewhere the refuse material is discharged by a flow of water, therebyobviating the necessity of pressure to immerse the material to beseparated.

The advantages of my machine are that it may be made portable, cheap,and durable, of any desired size, and of any suitable material, is notliable to incrustation, or waste of the mercury, While it thoroughlySAMUEL MAN.
